Errors creating buy x / y

In creating these, no matter what the product, I keep getting this error: "please enter a valid value" in red with a red box around the screen. I'm putting in 1 for the product, and selecting the product, and selecting include, but still getting this error both both the buy x and the get y fields

Hello,

If you are using version 2.4.7, then please update to 2.4.7.1. It has the fix for this.
